I’d like to use your location beacons as GPIO outputs to other devices.
My usecase(short version): I have a very-low power device that needs to turn on when a user, says to my raspberry pi: “Turn on device.” Its battery operated, and I’m hoping one charge will last a month.
Which means, I want the Raspberry PI to send off a BLE packet of some sort (I assume a GATT update) to your device, and cause the GPIO to go high briefly, then turn off, perhaps with another GATT update.
Is this possible? Can I manipulate characteristics to turn on GPIO? Or can I send something to the location beacon to have it turn on the GPIO?
Specs - the raspberry pi is plugged in - so it can output as much radio as needed. The beacon will be connected to the battery operated device. I’m basically hoping I can get your beacons to be my BLE remote. This has to run on linux if possible. Running Android or IOs doesn’t work from my project.
Thanks in advance!
